Abstract: The chromatographic fingerprint of Lingtoudancong Oolong tea was studied by high performance liquid chromatog- raphy (HPLC). According to the relative retention value, the relative area, common peaks, and overlap rate, the eight strong peaks and their relative total area resultants in HPLC were assayed respectivly. The chromatographic fingerprint of Lingtoudancong Oolong tea was analyzed and studied comparatively. The results showed that this method provided useful information for identification of tea variety, and a new way to study tea variety and quality by the chromatographic fingerprint was founded.

Key words: Lingtoudancong Oolong tea, high performance liquid chromatography, chromatographic fingerprint
